I am going to get the Eibach Pro Kit springs for my 92 Camaro RS, is there anything else I should buy/replace while I am doing this? Also, what is the typical cost for install on these?

Thanks.

 

an adjustable panhard bar would be a good choice because when you car sits down on the new lower springs, the body will shift to the passenger side. the pan hard rod will allow you adust this, it also improves handling greatly.

 

Lowering the car by itself will improve handling quite a bit. But along with lowering comes other options to increase it even more. I would say to first start with the easier. Since the front control arms will have to be dropped you may want to have new bushings installed such as ES or to go an even better route you may want to go with global west del-a-lum bushings, but these are a little pricey. Also because your lowering the car it's going to change the geometry so LCA relocating brackets are recommended but these require welding, and like mentioned before an adjustable panhard bar would also help to correct it. This is where I would start. Then maybe go with a stiffer shock like Bilstein or Koni, and a pair of adjustable LCA's

I'm not sure what the cost would be to install a set of springs. You may want to try doing it yourself and save the money for other upgrades. If you can get the springs out yourself you can take the A-arms to a machine shop and have them press the new bushings in for you which would cost around 10 bucks a bushing. Installing a set of lowering springs is eaiser than installing a set of original height springs.
